Elton John suffered a “potentially deadly” bacterial infection during a tour, forcing him to spend two nights in intensive care and cancel concerts in the United States, his management says.

The singer became violently ill at the end of a tour of South America last week, requiring him to return to Britain for urgent treatment.

Nine concerts that were due to be staged in Las Vegas and California over the next two weeks have been canceled.

John is now resting at home.

A statement by his management said infections of the kind suffered by the star were “rare and potentially deadly.” It gave no details.

“Thankfully, John’s medical team identified this quickly and treated it successfully. He is expected to make a full and complete recovery,” it added.

John is due to resume his schedule of live performances in Britain on June 3.

“I am so fortunate to have the most incredible* and loyal fans and apologize for disappointing them. I am extremely grateful to the medical team for their excellence in looking after me so well,” the star said.

His Million Dollar Piano tour is due to end its run in May 2018.

The career of John spans five decades and has been littered with accolades*, hit singles and world records.
